The Food and Agriculture Organization of the United Nations ( FAO, 1993) has indicated that there is an urgent need to match land types and land uses in the most practicable and logical way to continue a sustainable production and to meet the needs of society while conserving fragile ecosystems. Land evaluation is concerned with the assessment of land performance when used for a specified purpose ( FAO, 1977). In other words, land evaluation is likely to be the prediction of land potential for productive land use types, and then generally a comparison or match of the requirements of each potential land use with the characteristics of each kind of land. The results are a measure of the suitability of each kind of land use for each type of land (Dent, 1981; Beek, 1978).
